I don't think the custom resolution issue is that big of a problem. People having been using Windows media players for years without ever noticing the odd frame drop or repeat. It is sometimes in your head. The newest Nvidia driver should give you one frame drop or repeat every 12-14 minutes.

I have the latest nvidia driver and i'm getting 1 frame drop or repeat every 4min. Did nvidia fix only the timing of hd resolution? because i'm using 2160p.

thanks 

 You might need a clean driver install. Or your equipment isn't syncing as well. The clock variation problem isn't limited to video drivers alone. The CRU approach might be worth trying. You definitely need a clean driver install in that case.
